I really should read up and educate myself more on quantum physics. My knowledge consists of the information discussed in the book Time Travel: A Guide for Beginners. However, this video piqued my interest, so I will be doing further research in the coming weeks and months. This video is a quick introduction to quantum physics and the double slit experiment. As one said about the behavior of electrons, before the electrons are observed, there are infinite possibilities, but when the electrons are observed, a possibility becomes reality.
